i SHUTTLE-CHANGING Be it known that I, OSKAR .Lorzsoi-nua subject of the German; Emperor, Kresiding at Dresden, Saxony, Germany, have invent: ed a certain new and useful ImprovedShnt: tle-Ghanging. Mechanism for Looms, *of which the following is a specification,

This invention relates ,toaQdevicefor the automatic exchange of shuttles vinv weaving looms. i i 1 I the ccompany gd w ;.F 11l l is a side. elevation, Fig.2 a front elevation, and Fig. 3 a plan of an embodiment of the As soon as the material in the shuttle has, been exhausted to such an extent that a new shuttle with a full spool or pirn is to be introduced, the lever 66 is raised (dotted povice, such as a shaft similar to that described for instance, in the U. S. Patent to Wyman' quently the other end, which engages a recess 05 of the slide 0 is pushed out and the slide is set free, and the said slide will be tom f driven upward, and the empty shuttle, instead of being driven into the shuttle box, will now be driven under the raised portion of the shuttle box bottom f and out of the batten, the said shuttle falling into a box (not shown) arranged at the side. The batten has at that time reached its rearmost position. As soon as the slide 0 begins to rise, the spindle g which is supported below the batten in two bearings h, is' rotated, as the spindleg is provided with a cam i which rests on a roller 7cprovided on the slide 0. As soon as the spindle gis turned, the stop arm m secured to the spindle g, isturned downward, in order to form during the return a stop for the cam 0 rotatably mounted in a resilient manner on the oscillating hooked tension lever n. In

72 connected by lever arms to the eccentric p and controlled by the spring 9, is depressed by the cam 0 and coupled by the hook r and the bolt 3 to thejshuttle feedert The feeder t is mounted laterally on the loom and is guided in an overhanging portion arranged on the wall, of the loom, to

which, overhanging. portion is: secured the shuttlemagazme' a. As soonas the feeder t-is connected tothe eccentric p by the lever 7 arms and driven, the lever w} resting on the same and controlled by the spring a, will. be lowered together with the tongue g lwfith closing-hooks, mounted; on the same spindle r,-and the- -closing flap A which was -hith-,. erto locked,,1s released. Thefeeder t pulledv toward the batten, takes one shuttle from v 'theinagazine a and forces upwardthe flap A whichcloses the magazine at the bottom 'and is pivoted at both sides, and engages under the cam C arranged on the front shuttle box wall B, whereby the wall 13 of the shuttle box is forced torise with the q flap A, in order to enable the shuttle to slide freely into the shuttle box. The feeder t has then introduced a new shuttle. At the same tlme the part f of the'shuttle box bottom is brought into its former position owing to the sliding bracket D secured to the feeder t, striking the lever Z and forcing the latter back, whereby the spindle g and the cam z are turned downward, and the stop arm m upward, the slide c'being pulled downward by the cam 2' by means of the ble armed lever pivoted on the batten, a

lever adapted to strike the double armed lever, a slide which is set free by said double armed lever, an .inner part of the shuttle box bottom which is driven upward by said slide, a spindle provided with an arm resting on a roller provided on said slide, a stop arm secured to said spindle, a cam whichis engaged byv the stop arm when the battenfmoves forward, a hooked lever on whichthe cam is pivotally mounted, an eccentric for oscillating said lever, a feeder pulled toward the batten by the hooked lever, a lever operating a closing'fiap for the shuttle magazine and resting on the feeder, a shuttle box, means whereby theshuttle box isforcedjto open when the flap for the shuttlemag'a'zine rises and means whereby lever adapted to strike the double armed,

lever, a slide mounted in the batten which is set free by said double armed lever,an

inner part of the shuttle box bottom which is'driven upward b said slide,- a spindle, a pair of bearings supporting said spindle, an arm on said spindle, a roller provided on said slide, said arm resting on said roller, a stop arm secured to said spindle, a cam which is engaged by the stop arm when'the batten moves forward, a-hooked lever positioned by said cam, an eccentric for oscillating said lever, a shuttle feeder engaged flap for the shuttle magazine, a hook looking the closing flap and coupled to the double armed lever, a shuttle box, a movable front wall to the shuttle box and arms ar ranged thereon whereby said wall is forced to rise with the closing flap, and means for returning the parts to their normal for the purpose'set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
